A work in progress. Scratch with an XY pad.
Still toying with best way to implement this, but the guts are here. JUST BECAUSE WE CAN, for science. Touching the XY pad is like touching your record on the turntable to stop it. You can then make a circular motion forward or backward to scratch through the sample. Disengaging the XY pad picks up the loop in sync.
you could take this and double it and do real beat juggling, fading back and forth between which flexi/turntable pair is heard with the scene crossfader.
